UNCLASSIFIED. Looking for buyers.
What a revelation for me.
Radio-navigational jammers [Ground positioning system] much more widespread and liberally used than what I had ever believed.
From the qsl.net web site we have a description of a Russian GPS jammer as was marketed in 1997 and evidently widely used by the Iraqi during the Second Gulf War.
Used but apparently to no avail.
"Russian GPS Jammer"
"SUBJ: RUSSIAN AVIACONVERSIA PORTABLE GPS AND GLONASS JAMMER
"(U) CONFEX - THE RUSSIAN FIRM AVIACONVERSIA MARKETED AND DISPLAYED ITS PORTABLE GPS AND GLONASS JAMMER AT THE MOSCOW AIR SHOW '97, 19-24 AUG 97, IN MOSCOW, RUSSIA. THE 4-WATT JAMMER JAMS CIVILIAN AND MILITARY FREQUENCIES OF GPS AND GLONASS UP TO A RANGE OF 200 KM. PROTOTYPE AT THE SHOW - LOOKING FOR BUYERS."
This map purportedly shows the number and locations of GPS jammers that if used by the forces of Saddam would deny GPS guidance to American weapons systems. Cick on image to see a larger view.
Apparently this jammer used but again to no avail.
The jamming of GPS has BEEN TAKEN INTO CONSIDERATION BY AMERICAN WEAPONS SYSTEM DESIGNERS AND MILITARY PLANNERS AND PRECAUTIONS HAVE BEEN TAKEN!
Looking for buyers but caveat emptor. Buyer beware!
